No. Even Jesus was tempted.
Matt. 4:1 "Then was Jesus led up of the Spirit into the wilderness to be tempted of the devil."
Hebrews 4:15 (KJV) 5 For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.
"Temptation is not sin, and is no indication that God is displeased with us. The Lord suffers us to be tempted, but he measures every temptation, and apportions it according to our power to resist and overcome evil. It is in time of trial and temptation that we are enabled to measure the degree of our faith and trust in God, and to estimate the stability of our Christian character. If we are easily jostled and overcome, we should be alarmed; for our strength is small. Let us consider the words of comfort that have been left on record for our instruction: “There hath no temptation taken you but such as is common to man; but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.” God has apportioned the temptation in proportion to the strength he can supply, and he never permits us to be tempted beyond our ability to resist or to endure. “The Lord knoweth how to deliver the godly out of temptation.” “Blessed is the man that endureth temptation; for when he is tried, he shall receive the crown of life, which the Lord hath promised to them that love him.” Through prayer and the word of God we shall be enabled to overcome temptation." {ST December 18, 1893, par. 12}
"There are thoughts and feelings suggested and aroused by Satan that annoy even the best of men; but if they are not cherished, if they are repulsed as hateful, the soul is not contaminated with guilt, and no other is defiled by their influence." {RH March 27, 1888, par. 15}
What if we fall to temptation?
Repent, and do whatever you need to do to make things right, and return to Jesus! Don't wait to be on probation for a time.
1 John 2:1 "My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous."
"The means which God has provided to enable us to resist temptation are the study of his word, and earnest prayer. In his encounter with the prince of darkness in the wilderness of temptation, our Saviour prefaced every answer with the words, “It is written.” It was the word of God that vanquished Satan. Those who make that word their study are arming themselves with weapons of divine power against the attacks of the foe. “Thy word,” said the psalmist, “have I hid in my heart, that I might not sin against thee.” {ST March 25, 1886, par. 12}
"Even those who are striving in sincerity to keep the law of God, are not always free from sin. Through some deceptive temptation, they are deceived, and fall into error. But when their sin comes home to their conscience, they see themselves condemned in the light of the holy precepts of God’s law; but they do not war against the law which condemns them; they repent of their sin, and seek pardon through the merit of Christ, who died for their sins in order that they might be justified by faith in his blood. They do not avoid confession and repentance when the neglected law of God is brought to their attention, by exclaiming, as do the self-righteous pretenders to holiness, “I am sanctified, I am holy, and I can not sin.” This is the class whom the apostle rebukes; for he says, “If we say that we have no sin, we deceive ourselves, and the truth is not in us.” It is evident that where a claim to sinlessness is made, there the law of God has not been written in the heart; for the commandments of God are exceeding broad, and are discerners of the thoughts and intents of the heart. The apostle speaks words of encouragement to those who realize that they are sinners, and says, “If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.” “If we say we have no sin,” when our thoughts, words, and actions, reflected from the law of God, the great moral mirror, reveal us as transgressors, we make God a liar, and prove that his word is not in us." {ST April 30, 1896, par. 5}
