How to overcome Temptation?
Watch and pray, lest you enter into temptation; the spirit is willing, but the flesh is weak. Matthew 26:41
God does not tempt anyone, the Bible teaches us in Santiago James 1: 13-15 that:
"When you are tempted, remember not to say, 'God is tempting me.' God is never tempted to do evil, and he will never be tempting anyone. Temptation comes from our own desires, which seduce and draw us away. From those desires Sinful acts are born, and sin, when allowed to grow, gives birth to death. "
That is why we must constantly Pray, at all times, because when we pray our being will be in communion with God and therefore we will be less Vulnerable to yield to Temptation.
When you feel faint, that you no longer want to advance, that life is very hard and the burden is very heavy remember: Watch and Pray.
