God has given all those who really believe in God, and His Word, the wonderful mission of telling others to repent and trust in Christ Jesus. While God-hating cultures make that mission seem like a dirty secret or nasty mandate, Jesus made that command a commission clear to His disciples, after He rose from the dead and was about to ascend bodily into heaven. As they dined, Christ corrected their lack of understanding and reemphasized the message that He had been empowering them to fulfill the whole time that they were walking with Him during His earthly ministry. The eleven apostles dining with Jesus were, obviously, physically incapable of personally talking with every single soul throughout the whole world within their own lifetime, so, in line with numerous scriptures and examples throughout the Bible, that command automatically defaults to God's baseline of an ongoing commission to every believer to, likewise, go forth and continue telling other souls about God's singular salvation. The Old and New Testaments are loaded with examples that point out such principles, about trusting God alone for salvation, and sharing that with other people. That salvation is only available through Jesus Christ, as Isaiah 53 speaks of God's only Messiah, and as explained in Luke 1, Matthew 1-3, and Mark 1:1-11.
If we do not understand and accept that Jesus Christ is God in the flesh (the physical embodiment of God), then we cannot have adequate understanding of His sinless perfection and His ability to pay wholly and exclusively for our sin. Then, also, if we neglect to understand, acknowledge, and admit our lost spiritual condition, then we shall not be saved by any religious or other experiences.
14 Afterward he appeared unto the eleven as they sat at meat, and
upbraided them with their unbelief and hardness of heart, because they believed
not them which had seen him after he was risen.
And he said unto them, Go ye into all the
world, and preach the gospel to every creature.
He that believeth and is baptized shall be saved; but he that
believeth not shall be damned.
Earlier on, Jesus had to reinforce the foundation of the gospel message (among His followers) before He was crucified, because of the lack of understanding of His followers. Throughout the Bible, we see the repeated theme of human failure to understand, acknowledge, and act upon what God wants us to see, hear, and do in life.
31 Then he took unto him the twelve, and said unto them,
Behold, we go up to Jerusalem, and all things that are
written by the prophets concerning the Son of man shall be accomplished.
32 For he shall be delivered unto the
Gentiles, and shall be mocked, and spitefully entreated, and spitted on:
33 And they shall scourge him,
and put him to death: and the third day he shall rise again.
34 And they understood none of these things: and
this saying was hid from them, neither knew they the things which were spoken.
Even later on, as the faith of Christ, and biblical churches, spread abroad, the last apostle that Jesus 'hand-picked',
Paul, had to restate for the biblical record, in 1 Corinthians 15, what the real gospel was, is, and always shall be. For without the foundational understanding that Jesus Christ is God in the flesh, coupled with "repentance toward God and faith toward the Lord Jesus Christ", there is no other way of salvation at all for anyone. If Christians do not share THAT two-pronged message with those around us, then we are not fulfilling the job that Jesus sent us out to do. In our neglect to share the message of the sinless Godhood of Christ coupled with repentance and faith in Christ, then we are telling them to, "Go to Hell".
1 Therefore we ought to give the more earnest heed to the things
which we have heard, lest at any time we should let them slip.
2 For if the word spoken by angels
was stedfast, and every transgression and disobedience received a just
recompence of reward;
3 How shall we
escape, if we neglect so great salvation; which at the first began to be spoken
by the Lord, and was confirmed unto us by them that heard him;
Sinless and holy, Jesus Christ Himself said plainly that He is THE ONLY hope of salvation. If we, who say we believe, do not take that clear message of His Deity and the human need for repentance and faith in Him, to everyone around us, in tune with God's Word and Holy Spirit, then we are failing to stand in our primary life's work assigned to us by our Creator, as we have previously read. He and His commission are also evidenced by His Creation, as testified in Old and New Testaments of the Bible. His true awesomeness (even to those who have not read His Word) commands our attention and our obedience, calling us to repentance and faith in God's one true salvation. Believe Him, for He cannot lie. And always be willing to tell others of their urgent need to be saved. Take godly heart, Christian, and let God do His work through you, for, surely, few among us have striven with sin to the point of our blood being shed. Furthermore, God's Holy Spirit says to every biblical believer...
Wherefore he saith, Awake thou that sleepest, and arise from the
dead, and Christ shall give thee light.
See then that ye walk circumspectly, not as fools, but as wise,
16 Redeeming the time, because the
days are evil.
17 Wherefore be ye not
unwise, but understanding what the will of the Lord is.
18 And be not drunk with wine, wherein is excess;
but be filled with the Spirit;
Speaking to yourselves in psalms and hymns and spiritual songs,
singing and making melody in your heart to the Lord;
20 Giving thanks always for all things unto God and
the Father in the name of our Lord Jesus Christ;
Therefore, let us go forth and do let God do the work, through us, that He wants accomplished.
